The most common all-wheel drive 6-wheel truck in the Soviet Army during the 1980s had a diesel engine and a cab-over-engine layout. Its serial production began in 1981 at a plant in Naberezhnye Chelny. The car was distinguished by its high reliability and off-road capability. The basic model was intended, first of all, for the transportation of personnel or cargo up to 6 tons. Since the mid-1980s, this car for some time was the main transport base of the Soviet Army and the main middle-class car for the installation of various types and purposes of superstructures. Variants with KUNGs are widespread - closed box bodies for the installation of special equipment and the transportation of personnel. One of these body types was the K4320D variant.
